Methyl 4,6-bis­(4-fluoro­phen­yl)-2-oxo­cyclo­hex-3-ene-1-carboxyl­ate

The 3-cyclo­hexene units adopt envelope conformations in each of the two independent mol­ecules that comprise the asymmetric unit of the title compound, C₂₀H₁₆F₂O₃. The dihedral angles between the two fluoro­phenyl rings are 79.7 (2) and 73.7 (2)° in the two mol­ecules. In one of the mol­ecules, two C—H groups of the cyclo­hexene ring are disordered over two sets of sites in a 0.818 (13):0.182 (13) ratio, the major and minor components corresponding to the two enanti­omeric forms of the mol­ecule. Weak inter­molecular C—H...O inter­actions help to stabilize the crystal structure.

S1. Comment

Cyclohexenones are efficient synthons for building spiro compounds (Padmavathi et al., 2001a) or as intermediates in the synthesis of benzisoxazoles or carbazole derivatives (Padmavathi et al., 1999; 2000; 2001b). Cyclohexenone derivatives are well known lead molecules for the treatment of inflammation and autoimmune diseases (Kolesnick & Golde, 1994; Tanaka et al., 1997; Hoye & Tennakoon, 2000; Hiromichi et al., 2002).

The crystal structures of some cyclohexenone derivatives viz, (8RS,9SR)-ethyl 4-(3-bromothien-2-yl)-6-(2-furyl)-2-oxocyclohex-3- ene-1-carboxylate, (7RS,8SR)-ethyl 6-(1,3-benzodioxol-5-yl)-3-(3- bromo-2-thienyl)-2-oxocyclohex-3-ene-1-carboxylate, ethyl 4-(3-bromo -2-thienyl)-2-oxo-6-phenylcyclohex-3-ene-1-carboxylate, rac-ethyl 3-(3-bromo-2-thienyl)-2-oxo-6-(4-propoxyphenyl)cyclohex-3-ene-1- carboxylate (Fischer et al., 2007a,b; 2008a,b) and ethyl 6-(6-methoxy-2-naphthyl)-2-oxo-4-(2-thienyl)cyclohex-3-ene-1- carboxylate (Li et al., 2009) have been reported. In a continuation of our work on cyclohexenone derivatives (Ashalatha et al., 2009; Sreevidya et al., 2010) and in view of the importance of these derivatives, the title compound (I) is synthesized and its crystal structure is reported here.

The asymmetric unit of the title compound consists of two crystallographically independent molecules, A and B (Fig. 1). The cyclohex-3-ene units in both molecules adopt envelope conformations with puckering parameters Q = 0.462 (4)Å, Θ = 128.3 (5)° and ϕ = 165.2 (6)° for molecule A and Q = 0.488 (6)Å, Θ = 128.5 (6)° and ϕ = 164.2 (7)° for molecule B (Cremer & Pople, 1975). The two fluorophenyl rings are inclined to each other forming dihedral angles of 79.7 (2)° (C1A–C6A:C13A–C18A) in molecule A and 73.7 (2)° (C1B–C6B:C13B–C18B) in molecule B.

The cyclohexene rings (C7–C12) are almost coplanar with C7A, C12A, C7B and C12B displaced by -0.322 (4)Å, 0.262 (4)Å, -0.339 (6)Å and 0.281 (5)Å. In molecule B, C7 and C12 are disordered over two sites with a 0.818 (13):0.182 (13) ratio and the minor disorder component shows displacements from the mean plane of C8B/C9B/C10B/C11B in the opposite sense to that of the major component: C7C = 0.33 (4)Å; C12C = -0.414 (18)Å. Atoms C7A, C12A, C7B and C12B are stereogenic centres. In molecule B, the major and minor disorder components correspond to the two enantiomeric forms of the molecule.

In the crystal packing (Fig. 2), the molecules are linked through weak intermolecular C8A—H8AB···O2B; C8B—H8BB···O2A and C15B—H15B···O1B hydrogen bonds (see Table 1).

S2. Experimental

A mixture of (2E)-1,3-bis(4-fluorophenyl)prop-2-en-1-one (2.24g, 0.01mol) and methyl acetoacetate (0.01 mol) were refluxed for 2 hr in 10-15 ml of ethanol in presence of 0.8 ml 10% NaOH. The reaction mixture was cooled to room temperature and the solid product obtained was filtered and recrystallized from toluene (M.P.: 417K). Analytical data: found (calculated): C % : 70.08 (70.17); H% : 4.66 (4.71)

S3. Refinement

Atoms C7B and C12B and their attached H atoms are disordered over two sets of sites with a 0.818 (13):0.182 (13) occupancy ratio. All hydrogen atoms were positioned geometrically [C–H = 0.93 or 0.96Å] and were refined using a riding model, with U_iso(H) = 1.2 or 1.5 U_eq(C). A rotating group model was applied to the methyl groups. In the absence of large anomalous dispersion, 3128 Friedel pairs were merged for the final refinement.

Special details

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > 2σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
